Abstract
A method begins by one or more processing modules of one or more computing devices of a dispersed storage network (DSN) determining that dispersed error encoded data slices stored in a plurality of distributed storage units of the DSN are to be updated and then sending a plurality of lock requests respectively to the plurality of distributed storage units. The method continues with the processing modules receiving a response from a write threshold number of distributed storage units of the plurality of distributed storage units that a lock request has been granted by each of the write threshold number of distributed storage units and then sending a persist message to each of the write threshold number of distributed storage units from which the lock request has been granted.
